The BLOX Racing Performance Intake Manifold significantly improves the engine's overall flow characteristics compared to the factory unit. The latest aluminum casting technology allows BLOX Racing to create a smoother internal plenum, to maximize wave scavenging, and reduce the manifold's overall weight. Each application features a larger plenum and longer runners that have been balanced and tuned for peak power at higher RPM's.
All BLOX Racing Performance Intake Manifolds accept factory or aftermarket throttle bodies, and reuse all factory sensors.
For maximum results, use with BLOX Racing billet throttle bodies.
It is a nice piece. I am a little critical when installing parts. I port matched the manifold to a Proffesional Products throttle body. It was pretty close to matching, but this is 2 aftermarket parts, so that has to be taken into account. The upper intake manifold studs were a little short, so I had to get some hardware that was a little longer. Otherwise, the price for the part dcannot be beat. It is all install and running strong.
